I setup AWS VPN, and want to connect my peplink to the VPN. The peplink is Peplink Balance 20. The AWS don’t provide peplink configuration file, so I download the generic conf.
I have the generic file, and how to configurate my peplink?

VPN Connection Configuration
================================================================================
AWS utilizes unique identifiers to manipulate the configuration of
a VPN Connection. Each VPN Connection is assigned a VPN Connection Identifier
and is associated with two other identifiers, namely the
Customer Gateway Identifier and the Virtual Private Gateway Identifier.
Your VPN Connection ID : vpn-my
Your Virtual Private Gateway ID : vgw-my
Your Customer Gateway ID : cgw-my
A VPN Connection consists of a pair of IPSec tunnel security associations (SAs).
It is important that both tunnel security associations be configured.
IPSec Tunnel #1
================================================================================
#1: Internet Key Exchange Configuration
Configure the IKE SA as follows:
Please note, these sample configurations are for the minimum requirement of AES128, SHA1, and DH Group 2.
You will need to modify these sample configuration files to take advantage of AES256, SHA256, or other DH groups like 2, 14-18, 22, 23, and 24.
The address of the external interface for your customer gateway must be a static address.
Your customer gateway may reside behind a device performing network address translation (NAT).
To ensure that NAT traversal (NAT-T) can function, you must adjust your firewall !rules to unblock UDP port 4500. If not behind NAT, we recommend disabling NAT-T.
- Authentication Method : Pre-Shared Key
- Pre-Shared Key : presharekeystring
- Authentication Algorithm : sha1
- Encryption Algorithm : aes-128-cbc
- Lifetime : 28800 seconds
- Phase 1 Negotiation Mode : main
- Perfect Forward Secrecy : Diffie-Hellman Group 2
#2: IPSec Configuration
Configure the IPSec SA as follows:
Please note, you may use these additionally supported IPSec parameters for encryption like AES256 and other DH groups like 2, 5, 14-18, 22, 23, and 24.
- Protocol : esp
- Authentication Algorithm : hmac-sha1-96
- Encryption Algorithm : aes-128-cbc
- Lifetime : 3600 seconds
- Mode : tunnel
- Perfect Forward Secrecy : Diffie-Hellman Group 2
IPSec Dead Peer Detection (DPD) will be enabled on the AWS Endpoint. We
recommend configuring DPD on your endpoint as follows:
- DPD Interval : 10
- DPD Retries : 3
IPSec ESP (Encapsulating Security Payload) inserts additional
headers to transmit packets. These headers require additional space,
which reduces the amount of space available to transmit application data.
To limit the impact of this behavior, we recommend the following
configuration on your Customer Gateway:
- TCP MSS Adjustment : 1379 bytes
- Clear Don't Fragment Bit : enabled
- Fragmentation : Before encryption
#3: Tunnel Interface Configuration
Your Customer Gateway must be configured with a tunnel interface that is
associated with the IPSec tunnel. All traffic transmitted to the tunnel
interface is encrypted and transmitted to the Virtual Private Gateway.
The Customer Gateway and Virtual Private Gateway each have two addresses that relate
to this IPSec tunnel. Each contains an outside address, upon which encrypted
traffic is exchanged. Each also contain an inside address associated with
the tunnel interface.
The Customer Gateway outside IP address was provided when the Customer Gateway
was created. Changing the IP address requires the creation of a new
Customer Gateway.
The Customer Gateway inside IP address should be configured on your tunnel
interface.
Outside IP Addresses:
- Customer Gateway : my_public_ip
- Virtual Private Gateway : aws_vpg_ip_1
Inside IP Addresses
- Customer Gateway : 169.254.25.22/30
- Virtual Private Gateway : 169.254.25.21/30
Configure your tunnel to fragment at the optimal size:
- Tunnel interface MTU : 1436 bytes
#4: Border Gateway Protocol (BGP) Configuration:
The Border Gateway Protocol (BGPv4) is used within the tunnel, between the inside
IP addresses, to exchange routes from the VPC to your home network. Each
BGP router has an Autonomous System Number (ASN). Your ASN was provided
to AWS when the Customer Gateway was created.
BGP Configuration Options:
- Customer Gateway ASN : 65000
- Virtual Private Gateway ASN : 10124
- Neighbor IP Address : 169.254.25.21
- Neighbor Hold Time : 30
Configure BGP to announce routes to the Virtual Private Gateway. The gateway
will announce prefixes to your customer gateway based upon the prefix you
assigned to the VPC at creation time.
